Is it possible to get the seed when using the new Math.seedrandom() approach #27

Closed CuAnnan closed 9 years ago

I'm trying to keep some things seeded pseudorandom so as to make it easy to save them.

But I want to keep the Math.random as is.

Is it possible to have the best of both worlds and get the seed generated when using new Math.seedrandom approach?

Have been behind on github issues. The answer you're looking for is in the README.md:

The "pass" option can be used to get both the prng and the seed. The following returns both an autoseeded prng and the seed as an object, without mutating Math.random:

var obj = Math.seedrandom(null, { pass: function(prng, seed) {
  return { random: prng, seed: seed };
}});
